Hi, all:
Currently info mtre prints the memory-region hierarchy using two spaces as
indentation, which is not very clear when there are too many nodes.
```
(qemu) info mtree
memory-region: system
0000000000000000-ffffffffffffffff (prio 0, i/o): system
0000000000001000-000000000000ffff (prio 0, rom): riscv_virt_board.mrom
0000000003000000-000000000300ffff (prio 0, i/o): gpex_ioport_window
0000000003000000-000000000300ffff (prio 0, i/o): gpex_ioport
...
0000000040000000-000000007fffffff (prio 0, i/o): alias ...
0000000080000000-0000000087ffffff (prio 0, ram): riscv_virt_board.ram
0000000400000000-00000007ffffffff (prio 0, i/o): alias ...
```
Therefore, I optimized the print format of this command to be similar to the
tree command, so that it can better distinguish multi-level memory-region nodes.
```
(qemu) info mtree
memory-region: system
│ ├── 0000000000000000-ffffffffffffffff (prio 0, i/o): system
│ │ ├── 0000000000001000-000000000000ffff (prio 0, rom):
riscv_virt_board.mrom
│ │ ├── 0000000003000000-000000000300ffff (prio 0, i/o): gpex_ioport_window
│ │ │ └── 0000000003000000-000000000300ffff (prio 0, i/o): gpex_ioport
...
│ │ ├── 0000000040000000-000000007fffffff (prio 0, i/o): alias ...
│ │ ├── 0000000080000000-0000000087ffffff (prio 0, ram): riscv_virt_board.ram
│ │ └── 0000000400000000-00000007ffffffff (prio 0, i/o): alias ...
```
